| Summary: | Sloshing refers to less frequent vibration of free liquid surface within a specific stuffed vessel. The study mainly aims to contribute to forecast as well as sloshing monitoring. There are a number of applied factors involved in stimulation of this complicated problem, including littoral safeguard as well as coastwise structural designing for LNG/oil sloshing in containers. The forecast and monitoring of sloshing play a significant role in ensuring secured operating of applied engineering foundation. ANSYS-FLUENT can be used for flowing condition.
Liquid sloshing behaviour in a 2-D rectangular tank was simulated using ANSYS-FLUENT software subject to single or multiple-coupled external excitations. The volume of fluid (VOF) method was used to track the free surface of sloshing. External excitation was imposed through the motion of the tank by using the dynamic mesh technique. The complete setting procedures for rotation tank are present in this research through ANSYS-FLUENT and simulating outcomes for density, stress and variational speed as time goes by.
Keywords: liquid sloshing; computational fluid dynamics (CFD); dynamic mesh technique; Volume of fluid (VOF). |
